Saw some of the Women's Biathlon on NBC the other day. The rifles are facinating; they seem to be straight pull rifles of some sort with the bolt on a pivot. Pivoting the bolt up and back ejects the empty; forward and down loads the round. What kind of rifles are these? I've never seen them cataloged in the various Gun Digests. I have an Izmash Biathlon which works on a toggle, like a Luger turned on its side, but it's a sporting rifle, not a biathlon rifle, although it may be descended from one. Anyone know anything about biathlon rifles?
